Dominique Strauss-Kahn's accuser wasn't just a girl working at a hotel -- she was a working girl.

The Sofitel housekeeper who claims the former IMF boss sexually assaulted her in his room was doing double duty as a prostitute, collecting cash on the side from male guests, The Post has learned.

"There is information . . . of her getting extraordinary tips, if you know what I mean. And it's not for bringing extra f--king towels," a source close to the defense investigation said yesterday.

The woman was allegedly purposely assigned to the Midtown hotel by her union because it knew she would bring in big bucks. "When you're a chambermaid at Local 6, when you first get to the US, you start at the motels at JFK [Airport]. You don't start at the Sofitel," the source said. "There's a whole squad of people who saw her as an earner."

The woman also had "a lot of her expenses -- hair braiding, salon expenses -- paid for by men not related to her," the source said.

So she was literally a union whore. Is that what the last vanguard of the American working class is up to these days? And if it is a driver of union revenue, how long before we see Barack Obama start to talk about legalized prostitution as a revenue-enhancer and a job creator?

According to the two officials, the woman had a phone conversation with an incarcerated man within a day of her encounter with Mr. Strauss-Kahn in which she discussed the possible benefits of pursuing the charges against him. The conversation was recorded.

That man, the investigators learned, had been arrested on charges of possessing 400 pounds of marijuana. He is among a number of individuals who made multiple cash deposits, totaling around $100,000, into the woman’s bank account over the last two years. The deposits were made in Arizona, Georgia, New York and Pennsylvania.

The investigators also learned that she was paying hundreds of dollars every month in phone charges to five companies...

Friends in the clink? Six figures of cash in a "maids" bank account? A variety of different cell phone numbers? If it smells like cheap perfume and prophylactics...

The Daily Beast reports law enforcement sources say they have not come across anything to suggest a premeditated conspiracy. And that seems very likely to be true. It could be, after all, that DSK did in fact rape the randy maid. Or that he simply paid for sex, still a crime in America but de rigour in France. Or maybe the real crime was simply one of opportunity by the maid,who might have been short-paid, or simply saw a chance to add a few zeros to her bank account.

It looks less and less likely that DSK will even come to trial, as the last thing embattled New York DA Cy Vance Jr. wants is a third high-profile screwup of an open and shut case by his office.

But maybe he ought to find out how, exactly, a newbie at Local 6 wound up at one of the most prime pieces of real estate in the city. Who knew how she earned her spending money, and who was taking a piece of it? If the unions are now whoring out women to earn a little side cash for themselves, shouldn't that be investigated as well?

It should. But it won't, in a place like New York, where the entirety of the Democratic elected class is basically on the union payroll. And once Local 6 gets away with this crime, you can bet it will be repeated by service-workers unions nationwide.

....a proud memeber of SEIU Local 6?

Yet another act of misogyny by the left - against an immigrant women, no less! - that will be dismissed, because it serves their cause. Let's hope when the inevitable change in leadership comes, union thugs are held to account for the ruthless pimping of vulnerable women as well as their purchases of a differnt type of whore - Democratic politicians.
